摘要

This thesis investigates the performance of the Berdut linear motor for use in the propulsion of trains. This motor is part of a novel technology that uses an array of permanent magnets and iron-based materials in the stator combined with coils in the moving part that offer a simple and low-cost solution for transportation systems. Several topologies were considered, in order to gain a better understanding of the potential use of the technology for the propulsion of trains. The direction of permanent magnets and number of rails were modified from existing Berdut motors. The coils polarity switching was varied in an innovative effort to decrease power consumption and therefore increase efficiency. In order to model and analyze the motor, finite element simulations were run. A total of seven different topologies were assessed. Results from model options explored indicate that the topology titled: One single rail with a common nucleus was the best in terms of thrust force and the topologies titled: Out-of-phase and In-phase switching without irons offered superior performance in terms of efficiency when compared with the Berdut classic pole. In addition, the motors are more efficient with less coil turns in the moving part. Others studies were the effect of time step, mesh size and ripple.
